32 Channel RS485 RTU Control Board — 12V, 10A/250VAC Outputs, 180x90x20mm, UART

A compact RS485 RTU control board engineered for industrial and residential automation, offering 32 independently controllable channels. The module runs on 12V and provides outputs rated at 10A/250VAC, all packed into a space-saving 180x90x20mm unit. It supports six operational modes, including momentary, locking and delay commands with programmable delay up to 255 seconds. Communication is via RS485 bus with RTU compatibility and a UART port for plug-and-play connection to automation controllers; centralized management is supported through Poll software or other interface tools. Designed for automation engineers, developers and smart home installers, the board is suitable for coordinating security cameras, motorized door locks, LED lighting arrays, commercial building systems or automated residences while delivering precise synchronization and industrial-grade reliability.
